2.1Frame structure
Full welded steel structure, stress released , with rigidity and reliability well kept.
Main component is designed and Finite Element Analyzed through ANSYS software from USA.
Main frame composes of uprights, working table, holding-down beam and oil tank.
2.2 Upper blade beam and shearing angle
Guillotine type blade beam, with rake angle adjustable.
The rake angle adjusted through press button according to material and thickness.
When shearing thin thickness sheet, the rake angle could be reduced, thus the distortion of the product and
the burr could be minimized.
2.3 Shearing Blades
Exchangeable Rectangle blade, with 4 Cutting edges available on each blade.
Blade material 6CrW2Si with hardness HRC56-60, with quality shearing result and long life.
2.4 Shearing length/stroke adjustment
The Shearing stroke could be adjusted through knob according to the length of the product..
Thus efficiency and productivity could be improved when cutting shorter length product.
2.5 Cutting beam guiding and blade clearance
The cutting beam is guided between roller guides. At the rear of the cutting beam there are two sets of
upper and lower roller guides located at each end of the beam.
Two spring-loaded rollers located at the front of the shear apply pressure to the cutting beam, forcing it
against the back roller guides.
The bearings of the upper roller guides at the back of the cutting beam are mounted on an eccentric shaft.
Rotating this shaft causes the cutting beam to tilt, thus providing proper blade clearance to the shearing
blades.
The upper cutting beam inclined forward, with high section-cutting quality on the product.
The blade clearance adjustment is motor driven. The blades clearance could be adjusted according to
material and thickness.
2.6 Shadow Line Lighting
It is clear with shadow line lighting for a close and accurate view of the cutting line.
2.7 Hydraulic System
Compact hydraulic system for is adopted. Integrated mono-block valve group and worldwide famous valves
and seals are adopted for reliability, and the pipeline and connections are reduced to the minimum level to
ensure minimum maintenance.
With in-series cylinders to achieve good synchronization movement of the top blade beam.
The sheet is pressed by hold-down cylinders before shearing for safety and reliability during shearing.
Over-load protection for the safety of hydraulic system by adopting relief valve.
Hydraulic valve is from REXROTH, Germany or VICKERS, USA
Oil seals from NOK, Japan or MERKEL, Germany. With minimum wear and tear, no oil leakage.
High-pressure internal gear pump from VOITH, Germany or NACHI, Japan, with reliability, efficiency and
low noise.
2.8 Hydraulic Cylinder and Piston
The following process guarantee the quality of the main cylinder: Hammer hot forging---Rough shaping--
-precision machining by CNC Lathe---CNC Cylindrical Grinding for roundness---Super fine machining on
horning machine for smoothness.
The following process guarantee the quality of the main piston: Hammer hot forging---Rough shaping---
precision machining by CNC Lathe--- Hardening---- CNC Cylindrical Grinding for roundness--- vibration-
assisted grinding on horning machine for smoothness.
